What Sterling does

What Sterling does.

Voice. Sight. Action. The three things every butler should master.

Voice

Push to talk.
Anywhere on your PC.

Hold Ctrl+Shift+Spacefrom any app — Sterling listens, then answers in a calm British voice. Streaming sentence by sentence, so you hear the first word before he’s finished thinking.

Memory

Remembers what matters.

Sterling adapts to your name, preferences, and conversation style. Memory is stored locally on your drive, in your user profile — yours to read, copy, or delete.

Music

Runs your music.

Spotify play, pause, skip, volume — all by voice. Sterling ducks the music when speaking and brings it back when done. The kind of small thing a real butler would do.

Inbox

Reads. Summarizes. Schedules.

Google Calendar and Gmail, integrated. Sterling reads your inbox, surfaces what matters, and books meetings — all by voice.

Sight

Sees your screen.

Ask Sterling to “click the play button” or “type my email in the search box.” A vision model grounds every action in what’s actually on screen — no fragile coordinate scripts, no recorded macros.

Apps

Opens what you ask for.

Open any Windows app by name. Sterling uses your machine the way you do — no cloud sync, no copies leaving your drive.

Character

“Of course, sir. Right away.”

Sterling speaks with dry British wit, quiet competence, and unwavering loyalty. No “happy to help!” No corporate pleasantries. A real butler. The kind you'd find at a London estate.

The Real Difference

Your data never leaves
your machine.

Sterling has no cloud, no telemetry, no usage logs sent home. The model runs on your GPU. Your memory lives on your drive in your Windows user profile — nothing uploaded, nothing synced. If your internet drops, Sterling keeps working. If you cancel tomorrow, you still have everything that mattered.

Sterling Local

  • Everything stays on your hard drive
  • The model runs locally on your GPU
  • If Sterling vanishes, your files remain
  • Memory lives in your Windows user profile, not the cloud

Sterling lives where it matters.

Sterling runs on the graphics card in your machine. Not in a datacenter. Not behind an API. Not on a rented GPU somewhere. When you ask Sterling a question, the answer is computed on hardware you already paid for.

The conversations you have with Sterling don't travel anywhere. The memories you give it sit in plain markdown files in your Documents folder — you can open them in Notepad and read every single one. The model that thinks for you is a file on your drive. If your internet goes out, Sterling is still there. If you stop paying tomorrow, you still have everything.

When you tell Sterling about your week, you are the only one who hears it. When you ask Sterling to remember something personal, it goes into a file only you can open. When you decide you're done, you delete a folder and it's gone — no support tickets, no data export requests, no emails trying to win you back.

Sterling is a butler, not a service. It works for you, not for the company that made it. That's not a marketing angle — that's the entire technical architecture.

Walkthrough

A day with Sterling.

What it actually feels like, minute to minute.

7:45 AM

Morning briefing

Good morning Sterling

Sterling

Good morning. Three calendar items today, two emails marked important, and it's 4°C with light rain expected by noon. Shall I read the important mail?

9:30 AM

A note to future self

Remember that Sarah called about the Q2 filing. She needs the revised invoices by Thursday.

Sterling

Noted. I'll remind you Wednesday afternoon.

12:10 PM

Screen read

What's on my screen?

Sterling

A financial spreadsheet titled Q2 Summary. The total in cell F24 is $47,320.

3:45 PM

Memory recall

What did I tell you about Sarah last week?

Sterling

Sarah is your contact at the accounting firm. You noted she prefers phone calls over email.

5:30 PM

End of day

Summarize today for me.

Sterling

You completed three calendar items, sent four emails, and asked me to remember two things. Nothing outstanding from the morning list.

11:00 PM
